The word(s) "insult" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) O ye who believe! Be ye not like those who vexed and insulted Moses, but Allah cleared him of the (calumnies) they had uttered: and he was honourable in Allah's sight.

(2) And remember, Moses said to his people: "O my people! why do ye vex and insult me, though ye know that I am the messenger of Allah (sent) to you?" Then when they went wrong, Allah let their hearts go wrong. For Allah guides not those who are rebellious transgressors.
